METHODS: Intraoperative data were prospectively collected in 1080 patients undergoing pulmonary resection with OLV, intentional crystalloid restriction, and mechanical ventilation to maintain inspiratory peak airway pressure <30 cm H2O. Other ventilator settings and all aspects of anesthetic management were at the discretion of the anesthesia care team. We defined PLV and non-PLV as <8 or ≥8 mL/kg (predicted body weight) mean tidal volume. The primary outcome was the occurrence of pneumonia and/or acute respiratory distress syndrome (ARDS). Propensity score matching was used to generate PLV and non-PLV groups with comparable characteristics. Associations between outcomes and PLV status were analyzed by exact logistic regression, with matching as cluster in the anatomic and nonanatomic lung resection cohorts.

RESULTS: In the propensity score–matched analysis, the incidence of pneumonia and/or ARDS among patients who had an anatomic lung resection was 9/172 (5.2%) in the non-PLV compared to the PLV group 7/172 (4.1%; odds ratio, 1.29; 95% confidence interval, 0.48–3.45, P= .62). The incidence of pneumonia and/or ARDS in patients who underwent nonanatomic resection was 3/118 (2.5%) in the non-PLV compared to the PLV group, 1/118 (0.9%; odds ratio, 3.00; 95% confidence interval, 0.31–28.84, P= .34).

CONCLUSIONS: In this prospective observational study, we found no differences in the incidence of pneumonia and/or ARDS between patients undergoing lung resection with tidal volumes <8 or ≥8 mL/kg. Our data suggest that when fluid restriction and peak airway pressures are limited, the clinical impact of PLV in this patient population is small. Future randomized trials are needed to better understand the benefits of a small tidal volume strategy during OLV on clinically important outcomes.

Testimonials

“As Director of Surgical Services Departments there has been considerable changes have occurred in my department and Anesthesia Experts has always risen to meet our demands of our facility. They have been very pro-active in meeting the increase volumes allowing us to keep our surgeons and patients very satisfied with our services.”

“Before AE took over the anesthesia department was described by the surgeons as the worst in the history of our hospital. The prior management company was having a cancelled surgery per day. I am happy to report there has not been one since they have taken over the department. Additionally we have seen a 905 reduction if requested preop
lab tests. The anesthesia department is now the very best hospital department in our entire facility.”

“Anesthesia Experts has provided consistent anesthesia providers who display a high degree of integrity, responsibility and professionalism. They have become a more valuable part of our facility and community.”

LR CEO 150 beds TX

“Even though they are physically located 1000 miles away Anesthesia Experts just does not provide great anesthesia coverage they personally engage surgeons to increase their business. Last year my surgical volume rose by 24% and we are currently 50% ahead of last year and all of that growth is organic.”

JE FACHE CEO AL 92 bed hospital

“Anesthesia Experts is more responsive than anyone I have dealt with. They are available by phone whenever needed and will be on site for any need or request and has been on site to address issues before we can make the request.”

SW CEO 25 beds NM

“While problems are extremely rare when they do occur Anesthesia Experts quickly and professionally implements a solution. Our surgical volume has grown over 100 cases per month and now our GI docs want to perform all of their endoscopies in our hospital instead of their GI lab that they own!”

SP CEO 346 beds AL

“Our anesthesia department was a thorn in my side that kept me awake at night. Anesthesia Experts swept in and brought order to our mess and our department was quickly redirected.”
